Struct BedrockTextVectorizer 

pub struct BedrockTextVectorizer { /* private fields */ }

AWS Bedrock embedding adapter.

Uses the Bedrock Runtime InvokeModel API with SigV4 authentication. Each text is embedded individually since Bedrock does not support batch embedding.

Example

use redis_vl::vectorizers::{BedrockConfig, BedrockTextVectorizer, Vectorizer};

let config = BedrockConfig::from_env()?;
let rt = tokio::runtime::Runtime::new().unwrap();
let vectorizer = rt.block_on(BedrockTextVectorizer::new(config))?;

Implementations

impl BedrockTextVectorizer

pub async fn new(config: BedrockConfig) -> Result<Self>

Creates a new Bedrock adapter by building an AWS SDK client from the provided configuration.

This is an async constructor because the AWS SDK credential resolution is asynchronous.

Trait Implementations

impl AsyncVectorizer for BedrockTextVectorizer

fn embed<'life0, 'life1, 'async_trait>( &'life0 self, text: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<f32>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Embeds a single string asynchronously.

fn embed_many<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, texts: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Result<Vec<Vec<f32>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Embeds many strings asynchronously.

impl Debug for BedrockTextVectorizer
